How to Automatically Generate Image Alt Text with Content AI

Have you ever published a post in WordPress and later realized that you forgot to add alt text to your images?

It’s a common mistake, and it can happen to anyone. 

But guess what? We’ve made it incredibly easy for you to generate alternative texts (alt text) for your images using our Content AI directly on your WordPress dashboard.

How to Generate Image Alt Text with Content AI

In this knowledgebase article, we will explain how to use Content AI to generate alt text for your images in WordPress.

1 Why Should You Add Alt Text for Images?

Alt text, short for alternative text, is essentially a hidden description for an image on a webpage. It serves two crucial functions:

  • Accessibility: The alt text descriptions help people who rely on screen readers understand the content of your images, making your website inclusive for everyone.
  • SEO: Search engines use alt text to understand the content of your images and rank them in image search results. This can help more people discover your website.

2 How Does Content AI Generate Alt Text for Your Images?

Content AI will analyze the visual elements of your images and generate descriptive text that accurately represents the image. This will save you time while ensuring your images have appropriate, SEO-friendly alternative text descriptions.

This alt text generation feature seamlessly integrates with the WordPress Editor, allowing you to generate alt text for individual images or in bulk directly from the page/post editor or Media Library.

3 How to Use Content AI to Generate Alt Text for Images

To use Rank Math’s Content AI, you will need Content AI credits, with each generation consuming 50 credits. But don’t worry; if you ever run out of credits, you can always subscribe to a Content AI plan that suits your requirements.

First things first, ensure that you’ve enabled the Content AI module by navigating to Rank Math SEO → Dashboard in your WordPress admin area, as shown below.

Now, let’s explore the different ways you can generate alt text using Content AI:

3.1 Generating Alt Texts for Images From Your Page/Post Editor

Content AI seamlessly integrates with your workflow, allowing you to generate alt text for your images either while uploading or after uploading them to your post/page editor.

Here’s how it works:

When you upload images to Media Library from your WordPress Editor, as shown in the screenshot below.

Selecting the WordPress Media Library option

Simply select the image for which you want to generate alt text.

On the right side, next to the ‘Alt Text’ field, you’ll see a Generate Alt button with the Content AI logo. Click on it, and voilà! The AI will generate accurate and descriptive alt text for your image in seconds, as illustrated below.

After that, you can click the Select button to insert the image into your content.

Alternatively, if you’ve already inserted images into your post/page editor, you can still generate alt text for them. Simply click on the image and navigate to the image block settings. 

Then click the Generate Alt option next to the Alternative Text field. And in a few moments, Content AI will generate the alt text for the image, as illustrated below.

Once you’ve reviewed the generated alt text for accuracy, don’t forget to Publish/Update your post to save the changes.

3.2 Generating Alt Text to Images in Your Posts/Pages in Bulk Content AI

But what if you’ve already written your blog posts or completed the content on your posts/pages and want to add alt text to the images used retrospectively? Then, you can choose to do it in bulk with Content AI.

Content AI enables you to add alt text to all images in bulk across your posts or pages with just a few clicks.

To do this, you just have to navigate to the Pages or Posts in WordPress and select the pages or posts to which you want to add the alt texts to their images by checking the boxes before each. 

Selecting posts in WordPress

Once you’ve done that, click on the Bulk actions dropdown list and select the Write Image Alt Text with AI option, as shown below.

3.3 Generating Alt Texts for Images From Your WordPress Media Library

In addition to generating alt text for images from your post/page editor, you can also do so from your WordPress Media Library. 

To start, navigate to Media → Add New Media File from your WordPress dashboard.

Next, click the Select Files button to upload a new image file from your computer. After uploading the image, click on the Edit option next to it, as depicted below.
